Understanding Howler Systems in Fire Safety
Construction and temporary sites face distinct fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm network is essential for promptly alerting all personnel in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a flexible, customisable solution suitable for diverse environments.
Overview of HO Alarms?
HO alarms are battery-operated, standalone units intended for temporary spaces such as site cabins or unconnected site areas. No hard-wired connection is required, making installation straightforward.
- High output: Generally 102 dB at 1 metre.
- Visual indicators: Optional units feature a strobe light alongside the audible siren.
- Durable casing: Many are IP-rated for external or semi-exposed installation.
HO alarms extend main systems, securing areas not reached by the primary site alert infrastructure.
The Site-Wide Site Alert Systems
The Howler Site Alert system suits smaller and medium-sized sites. Each unit can work alone or be wired together with up to 20 others. When triggered, every linked alarm will sound and flash, ensuring comprehensive coverage.
- Audible warning: Approx. 100 dB at 1 m
- Visual cue: Built-in red LED beacon
- Best used where cable runs are straightforward
Site Alert RF
Where wiring is impractical, the Site Alert RF allows up to 30 devices to connect wirelessly to a master unit. With up click here to 1 km open-air range and multiple frequency channels, this setup is ideal for sprawling or temporary layouts.
Hybrid installations using both wired and wireless units are common and offer better coverage.
Using the GOLink System Effectively
GOLink acts as a radio-linked click here backbone, supporting site-wide communication and coordination.
System Integration
This module connects Howler alarms to external systems (e.g. CCTV, access control), allowing howler site alarms signals to cascade when an event occurs. Up to 127 stations can communicate over the GOLink network.
First Aid Alert Feature
Some models, such as the H05 GOLink, include separate fire and first aid switches. The latter sends a discreet assistance signal to a control point without triggering full evacuation unless specified.
Effective Site Planning Tips
- Zone planning: Map the site into clear zones (e.g. cabins, workshops) and position units for optimal reach.
- Wired & wireless balance: Use wired alarms where infrastructure allows; RF units in more mobile areas.
- Regular testing: Weekly or monthly inspections to confirm functionality and battery levels.
- Staff training: Ensure all personnel understand alarm tones, first aid indicators, and emergency response steps.
